In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
Referring to fig. 1, which is a schematic view of an implementation flow of an electronic red packet identification method provided in an embodiment of the present application, where the electronic red packet identification method is applied to a mobile terminal, as shown in the figure, the electronic red packet identification method may include the following steps:
step S101, when a preset application program receives information, converting the view of the information into a picture.
In the embodiment of the present application, the preset application refers to an application of a certain type or having a certain function selected by a user from applications installed in the mobile terminal, for example, an application having a function of generating an electronic packet, such as WeChat, Paibao, and QQ. Optionally, the user may modify the selected application according to actual needs.
In the embodiment of the application, when a preset application program runs in a foreground or runs in a background, whether the preset application program receives information or not is automatically monitored in the background, and when the preset application program is monitored to receive the information, a view of the information is converted into a picture; and when monitoring that the preset application program does not receive information, continuing monitoring. Wherein the view of the information typically consists of a plurality of first views, such as, for example, "get Red envelope", "WeChat Red envelope", "May you like to buy money, great benefit! "and red envelope small figures, etc. are all the first views of the electronic red envelope that constitutes the WeChat. Converting the view of the information into the picture may be to construct a bitmap, generate a canvas using the bitmap, and then draw the content of the view of the information onto the canvas.
Step S102, acquiring a color histogram of the picture.
The color histogram of the picture describes the proportion of different colors in the picture. The color histogram may be based on different color spaces and coordinate systems, such as RGB color space and HSV color space, among others.
When the color histogram of the picture is obtained, the color space can be divided into a plurality of small color intervals, each small interval becomes one bin of the histogram, the process is called color quantization, and the color histogram can be obtained by calculating the number of pixels of which the colors fall in each small interval.
Step S103, calculating the similarity between the color histogram of the picture and a first preset color histogram.
In this embodiment of the application, the similarity between the color histogram of the picture and the first preset color value histogram is used to indicate the degree of closeness between the color histogram of the picture and the first preset color value histogram, and 1-D may be used as the similarity between the color histogram of the picture and the first preset color histogram by calculating the euclidean distance D between the color histogram of the picture and the first preset color histogram.
The first preset color histogram refers to a color histogram of the electronic red packet information preset by a user, and the color histogram of the electronic red packet information may refer to a color histogram of a picture after a view of the electronic red packet information is converted into the picture. Optionally, the user may modify the set first preset color histogram according to actual needs.
It should be noted that the number of the preset application programs may be one or more, and when the number of the preset application programs is multiple, because the electronic red packet patterns corresponding to different preset application programs (for example, WeChat and QQ) may be different, in order to be able to identify the electronic red packet information received by different preset application programs, corresponding first preset color histograms may be set for the different preset application programs, that is, each preset application program has a corresponding first preset color histogram.
In this embodiment of the application, a corresponding relationship between M preset application programs and N first preset color histograms may be pre-established, before the similarity between the color histogram of the picture and the first preset color histogram is calculated, a first preset color histogram corresponding to the preset application program in step S101 may be searched from the corresponding relationship, and after the first preset color histogram corresponding to the preset application program in step S101 is found, the similarity between the color histogram of the picture and the first preset color histogram corresponding to the preset application program (i.e., the preset application program in step S101) is calculated. Wherein N is an integer greater than zero, and M is greater than or equal to N.
And step S104, if the similarity between the color histogram of the picture and the first preset color histogram exceeds a first preset threshold value, determining that the information is electronic red packet information.
In this embodiment of the application, after obtaining the similarity between the color histogram of the picture and a first preset color histogram corresponding to the preset application program, the obtained similarity between the color histogram of the picture and the first preset color histogram may be compared with a first preset threshold value to determine whether the color histogram of the picture matches the first preset color histogram, and if the similarity between the color histogram of the picture and the first preset color histogram exceeds the first preset threshold value, it is determined that the color histogram of the picture matches the first preset color histogram, where the information is electronic red packet information; if the similarity between the color histogram of the picture and the first preset color histogram does not exceed a first preset threshold value, it is determined that the color histogram of the picture is not matched with the first preset color histogram, and the information is not electronic red packet information. The first preset threshold is used for indicating whether the color histogram of the picture is matched with the first preset color histogram. The electronic red packet information includes, but is not limited to, money amount, electronic red packet picture, electronic red packet ID, etc., such as an electronic red packet sent by a WeChat friend or an electronic red packet sent by a member in a WeChat group, etc.
In the embodiment of the application, after the information is determined to be the electronic red packet information, if the mobile terminal is in the preset state, the electronic red packet information can be directly displayed on the screen of the mobile terminal and corresponding voice prompt information is sent out, so that a user can conveniently and quickly identify the electronic red packet. The preset state may refer to a state in which a user cannot constantly pay attention to a preset application program in the mobile terminal, and the preset state includes, but is not limited to, a screen-off state, a screen-locking state, a screen-on state, a background running of the preset application program, and the like. The voice prompt information is used for prompting the user that a red packet arrives.
According to the embodiment of the application, the similarity between the color histogram of the received image after information conversion and the first preset color histogram is compared, whether the received information is the electronic red packet information or not can be effectively identified, the influence of upgrading of a preset application program is avoided, the identification accuracy of the electronic red packet is improved, and the problems that in the prior art, after the application program is upgraded, the electronic red packet cannot be identified continuously, and the identification accuracy is low are solved.
Referring to fig. 3, which is a schematic view of an implementation flow of an electronic red packet identification method provided in the second embodiment of the present application, where the electronic red packet identification method is applied to a mobile terminal, as shown in the figure, the electronic red packet identification method may include the following steps:
step S301, when a preset application program receives information, acquiring the height h and the width W of a view of the information and the width W of the view of a first interface, wherein the first interface is an interface for displaying the information.
Illustratively, fig. 4 is an exemplary diagram of the wechat electronic red packet information, where h in fig. 4 is a height of a view of the wechat electronic red packet information, W is a width of the view of the wechat electronic red packet information, and W is a width of a view of an interface displaying the wechat electronic red packet information.
Step S302, calculating the ratio of the height h to the width w of the view of the information
And the ratio of the width W of the view of the information to the width W of the view of the first interface
Step S303, if the ratio is not equal to the predetermined value
Within a first predetermined range and a ratio
And if the information is located in a second preset range, converting the view of the information into a picture.
In the embodiment of the present application, after converting a view of information received by a preset application into a picture, a ratio of a height h to a width w of the view of the information may be determined

Within a first predetermined range and a ratio
Not within a second predetermined range, or said ratio
Is not within the first predetermined range and has a ratio
Within a second predetermined range, or said ratio
Is not within the first predetermined range and has a ratio
If the information is not located in the second preset range, the information is determined not to be the electronic red packet information, and at this time, the electronic red packet identification process can be ended. The first preset range and the second preset range are used for indicating whether the information received by the preset application program is possible to be electronic red packet information or not.
In this embodiment of the application, the electronic red packet types corresponding to different preset applications may be different, and then the heights and widths of the views of the electronic red packet information corresponding to different preset applications may also be different, because the settings of the first preset range and the second preset range are related to the heights and widths of the views of the electronic red packet information, different first preset ranges and different second preset ranges may be set for different preset applications, the first preset range in step S303 is the first preset range corresponding to the preset application in step S301, and the second preset range is the second preset range corresponding to the preset application in step S301.
Step S304, acquiring a color histogram of the picture.
The step is the same as step S102, and reference may be made to the related description of step S102, which is not repeated herein.
Optionally, the obtaining the color histogram of the picture includes:
and converting the picture from an RGB color space to an HSV color space, and acquiring a histogram of hue H in the HSV color space.
Compared with the RGB color space, the HSV color space can express the brightness, the tone and the vividness of colors very intuitively and is convenient for color comparison, so that when the color histogram of the picture is obtained, the picture can be converted from the RGB color space to the HSV color space, and the histogram of the tone H in the HSV color space is taken as the color histogram of the picture.
Step S305, calculating a similarity between the color histogram of the picture and a first preset color histogram.

In this embodiment of the application, whether the first picture exists in the picture may be detected after converting the view of the information received by the preset application into the picture, or whether the first picture exists in the picture may be detected after performing step S503, which is not limited herein. If the first picture exists in the pictures, converting the RGB color space of the first picture into HSV color space, and acquiring a histogram of hue H in the HSV color space; and if the first picture does not exist in the pictures, determining that the information is not the electronic red packet information. The first picture may refer to identification information capable of identifying whether the information is electronic red packet information, including but not limited to an electronic red packet picture in the electronic red packet information, such as the red packet small picture in fig. 2.
In this embodiment of the application, since the position of the first picture in the electronic red packet information is usually fixed, whether the first picture exists in the picture is detected, specifically, whether the first picture exists at a preset position in the picture is detected. Because the electronic red packet information has a specific view layout, whether the first picture exists in the pictures can also be determined by detecting whether a view corresponding to the first picture exists in views of information received by a preset application program.

Step S506, calculating a similarity between the color histogram of the first picture and a second preset color histogram.
In the embodiment of the present application, the same method as that used for obtaining the color histogram of the picture in the first embodiment may be used for obtaining the color histogram of the first picture, and details thereof are not repeated here. The method for calculating the similarity between the color histogram of the first picture and the first preset color histogram may be used in the calculation of the similarity between the color histogram of the first picture and the second preset color histogram, and details are not repeated herein.
